Deuteron production in central Pb+Pb collisions at 158A GeV
Experimental results on deuteron emission from central Pb+Pb collisions (E/sub beam/=158A GeV, fixed target), obtained by NA49 at the CERN SPS accelerator, are presented. The transverse mass m/sub t/ distribution was measured near mid-rapidity (2.0<y<2.5) in the range of 0<m/sub t/-m/sub 0/...

| description | Experimental results on deuteron emission from central Pb+Pb collisions (E/sub beam/=158A GeV, fixed target), obtained by NA49 at the CERN SPS accelerator, are presented. The transverse mass m/sub t/ distribution was measured near mid-rapidity (2.0<y<2.5) in the range of 0<m/sub t/-m/sub 0/<0.9 GeV/c/sup 2/ (0<p/sub t/<2.0 GeV/c) for the 4% most central collisions. An exponential fit gives an inverse slope T/sub d/=(450+or-30) MeV and a yield dN/sub d//dy=0.34+or-0.03. The coalescence factor B/sub 2/(m/sub t/=m/sub 0/)=(3.5+or-1.0).10 /sup -4/ GeV/sup 2/ and its m/sub t/-dependence are determined and discussed in terms of a model that includes the collective expansion of the source created in a collision. The derived Gaussian size parameter R/sub G/ of the emission volume is consistent with earlier HBT results on the source of pion emission. (28 refs). |
